Many 5 oz and 10 oz gold bars come sealed in tamper-evident assay packaging, which certifies the weight, purity, and authenticity of the gold. Bars from reputable mints such as PAMP Suisse, Valcambi, and the Royal Canadian Mint often include these security features. However, some secondary market bars may not include an assay card but are still rigorously tested for authenticity.
